The 'High School Musical' actress, 25, insists she will be walking down the aisle in front of her 28-year-old former co-star when she ties the knot with her fiancé Christopher French later this summer.

When asked if she was going to be a bridesmaid at the nuptials, Vanessa told E! News: "Of course I'm going to be a bridesmaid!"

Christopher proposed to Ashley last August after only eight months of dating, but Vanessa believes the loved-up duo are the perfect match because they bring out the best in each other.

She explained: "I think they just inspire each other. They're just great, I love him for her!"

In December, Ashley gushed about how "natural" and easy her relationship with the rocker was from the very beginning.

She said: "I've obviously been in long relationships in the past. But I think because of knowing what I wanted, I wouldn't have gone into a relationship if it wasn't what I wanted. I think from the moment that him and I met, I just knew it. I was like, 'Ok this is the guy,' and he knew the same thing. It doesn't get any better. I just can't explain it."

The actress previously revealed she and Christopher are planning to have a "small" and "private" ceremony when they get hitched.

Meanwhile, Vanessa is currently dating Austin Butler, but was previously in a long-term relationship with her and Ashley's other co-star Zac Efron, who sought treatment in rehab for a cocaine addiction last year.
